FBI files suggest the 1964 world title bout between Cassius Clay and Sonny Liston was not a fair fight and the Mafia may have been involved.
It's being billed as richest fight in history - it features the most highly paid sportsman in the world for the last three years
Mike Tyson has revealed that he is on the verge of dying from alcohol and drug abuse after years of lying about being sober.
British boxer Amir Khan beat his American opponent Luis Collazo on points in Las Vegas and has now set his sights on a future bout with the unbeaten Floyd Mayweather.
The judges scored the fight 117-106, 119-104 and 119-104 in the Bolton boxer's favour leaving open the possibility of a future fight with Mayweather - who also won last night at the MGM Grand.
Khan, who is unlikely to fight the unbeaten boxer in September because it is close to the Muslim fasting period of Ramadan, said after his fight: "I really believe I have the style to trouble Floyd Mayweather."
The government was defiant today after it emerged former boxing champion Mike Tyson was banned from entering the UK under new immigration rules.
Immigration Minister Mark Harper said the fact that the former heavyweight champion had been refused entry was "welcome" and proof that the Home Office was getting to grips with immigration. He said:
"The rules don't change just because the offender is famous.
"People have to obey the law, this Government makes no apology for toughening up the rules in 2012, and they will apply to people evenly, whether they are famous or not."
Mike Tyson has said changes to UK immigration law banning him from entering the country are "disheartening".
The former boxer is barred from the UK due to a six-year sentence for rape that he received in 1992.

I was greatly disappointed when I learned of United Kingdom's immigration law changes that went into effect December 2012.
I have been coming to the UK consistently in the past decade so this change is disheartening since it affects my current entry standing.
I apologise to my fans that were inconvenienced, however, please know I am currently working diligently with the proper authorities to regain access next year for my UK tour...
I have a great deal of respect for the laws of the United Kingdom and will continue taking the proper steps for re-entry.
Former heavyweight champion boxer Mike Tyson has said he was "greatly disappointed" when he learned he could not enter the UK and would "continue taking the proper steps for re-entry".
The ban on former boxer Mike Tyson from entering the UK is "mandatory" because of the length of his jail sentence for rape.
Under tougher immigration rules introduced in December 2012, there is "a mandatory refusal where a person has been convicted of an offence and sentenced to at least four years' imprisonment, at any point in the past."
Although Tyson only served three years in prison for the crime, he was sentenced to six years.
A campaign group that tackles disbelief around domestic and sexual violence has praised laws barring former boxer Mike Tyson from visiting the UK.
Ending Victimisation and Blame said the ban "sends a message" about the consequences of criminal actions.
– Spokesperson for Ending Victimisation and Blame
We are delighted that Mike Tyson is not being allowed into the UK due to his previous convictions, one of which was for rape.
We believe that this sends a message that his criminal actions have long-term consequences - sadly, the consequences for his victim seem to have been forgotten by both Mike Tyson and his supporters.
Former world heavyweight boxing champion and convicted rapist Mike Tyson has discovered he is banned from entering the UK.
The 47-year-old has cancelled a string of appearances in London as part of a promotional tour for his new book after finding out he was banned from Britain.
His publishers said recent changes to UK immigration rules, including any person sentenced to more than four years in prison being banned from Britain, meant he was unable to travel.
Tweets posted on Tyson's official Twitter account as recently as Friday suggest the boxer was unaware he would be hit by the changes. He wrote: "So, UK fans, who is brave enough to get in the ring and ask me a question?"
Tyson will now promote his autobiography Undisputed Truth in Paris.
Residents of the typhoon-devastated town of Tacloban in the Philippines enjoyed a few rare moments of exultation as boxing hero Manny Pacquiao defeated Brandon Rios of the US today.
Hundreds gathered in a park to watch their countryman clinch the WBO welterweight crown in Macau. The bout was streamed live onto a large screen for the crowd to see.
Tacloban was one of the first large settlements to be hit by Typhoon Haiyan, which left the town almost entirely flattened.
Debate raged on Twitter among boxing fans following Car Froch's controversial ninth round victory against George Groves in Manchester.
That Froch/Groves decision is a shocker! No way he will give him a rematch because he will get dusted.
Watched Froch Groves back ten times. Groves is gone, he's not defending, his head is rolling and he turns his back. Fight over
Groves impressed me , carried himself well. Froch, great boxer, not at the races tonight. Thought his post match lacked decorum.
